October 16th, 2018, Vancouver, BC – IDM Mining Ltd. (TSX.V:IDM) (OTCQB:IDMMF) (“IDM” or the “Company”) announces that underground drilling has commenced using two core rigs at the advanced-stage Red Mountain Underground Gold Project (“Red Mountain” or the “Project”), located west of Stewart, BC. An estimated 7,600 meters in over 30 holes are planned. The Company has a winterized camp and shop facility to support the program.

Exploration drilling during this program will primarily test four areas: a near-surface synform between the Marc and 141 Zones; the northern and western extensions to the Smit and JW Zones; a projected high-grade connection between the Smit and 141 Zones; and the northern and eastern extensions to the SF Zone antiform. Additionally, drilling will target conversion of inferred resources to measured and indicated classification, primarily within the Smit and SF Zones.

“With our EA Certificate recently received from BC’s Provincial Government,we are excited to be back drilling at Red Mountain, particularly to target areas identified by our geological team’s new interpretation of untested high-amplitude fold closures and limbs,” said Robert McLeod, President and CEO of IDM Mining. “Each drilling program to date has systematically added high-grade measured and indicated resources that are amenable to underground bulk-mining methods.”

It is expected that the drill program will be completed by early December, 2018.

Forward-Looking Statements: Some statements in this news release contain forward-looking information or forward-looking statements for the purposes of applicable securities laws. These statements include, among others, statements with respect to the proposed exploration and development activities and their timing, resource estimates and potential mineralization. These statements address future events and conditions and, as such, involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the statements. Such factors include, among others and in addition to those described elsewhere in this release, timing and success of future exploration and development activities, exploration and development risks, delays in obtaining or inability to obtain required government or other regulatory approvals, permits or financing, the risk of unexpected variations in mineral resources, grade or recovery rates, of failure of plant, equipment or processes to operate as anticipated, of accidents, labor disputes, and unanticipated delays in completing other development activities, the risk that estimated costs will be higher than anticipated and the risk that the proposed mine plan and recoveries will not be achieved, equipment breakdowns and bad weather, the timing and success of future exploration and development activities, exploration and development risks, mineral resources are not as estimated, title matters, third party consents, operating hazards, metal prices, political and economic factors, competitive factors and general economic conditions. In making the forward-looking statements, the Company has applied several material assumptions including, but not limited to, the assumptions that: required regulatory approval, permits and financing will be obtained; the proposed exploration and development will proceed as planned; with respect to mineral resource estimates, the key assumptions and parameters on which such estimates are based; that the proposed mine plan and recoveries will be achieved, that capital costs and sustaining costs will be as estimated, and that no unforeseen accident, fire, ground instability, flooding, labor disruption, equipment failure, metallurgical, environmental or other events that could delay or increase the cost of development will occur, and market fundamentals will result in sustained metals and minerals prices. The Company expressly disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise except as otherwise required by applicable securities legislation.
